83049-45-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83049-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,4 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83049-45:
(7*8)+(6*3)+(5*0)+(4*4)+(3*9)+(2*4)+(1*5)=130
130 % 10 = 0
So 83049-45-0 is a valid CAS Registry Number.

Nesvadba, Petr,Kuthan, Josef
, p. 1494 - 1502 (2007/10/02)
Oxidation of 1-substituted 2,4,6-triphenylpyridinium salts Ia-Ij with potassium ferricyanide in an alkaline medium was accompanied by contraction of the pyridine ring and formation of 1,2,3,5-tetrasubstituted pyrroles II.The derivative IIf underwent facil
